Well-executed design combined with solid, reliable performance make this Bosch belt sander a tool with noticeable performance advantages. The Bosch features a magnesium-and-plastic housing that's lightweight yet durable. The tool is nicely balanced, comfortable, and easy to operate--important features in a tool that's often used for long periods of time for removing large amounts of stock. The Bosch comes with a cast-aluminum platen--so there's none of the warping that affects stamped-steel platens--and it sands perfectly flat right out of the box. Like many of the sanders in this class, the motor on the 1274 is aligned with the belt edge to allow flush sanding into corners. The tool's only drawback is that visibility is limited when sanding into tight corners, but that's a small minus when weighed against all the pluses. The belt-changing system works well--we didn't suffer any spring pinches--and the tracking adjustment tracks the new belt quickly and keeps it in place. There's a variable-speed dial built right into the trigger switch, which makes adjusting the belt speed fast and convenient. Wood magazine tested 10 3-by-21-inch sanders and liked the 1274DVS best. We agree that it's a great tool. --Mark McDonald

Grinding Tools - The Different Types and Their Specific Applications

!±8± Grinding Tools - The Different Types and Their Specific Applications

Grinding tools, as the name implies, are machines used for grinding. Grinding is possible because of the presence of the so-called abrasive wheel. This is the main part of the grinding tool used for cutting. The role of the abrasive wheel is to make a cut on a particular surface of the material or work piece through the process known as shear deformation.

Aside from the grinding or abrasive wheel, the machine also has its own bed. The bed specifically functions for guiding and holding the material or work piece. Another part is called the grinding head that is important in controlling the force of the grinding tool to that of the work piece. At times, the grinding head may be fixed while it travels through the work piece or it may move while the work piece is left on a fixed position. Looking to specific types of grinding tools will allow better understanding of its applications.

Belt grinders

Belt grinders are specifically important in belt grinding processes. They function very well in metals with the presence of coated abrasives. The belt grinding process is regarded as a very versatile one because it is a very relevant method in almost all applications. Coated abrasives are also being used during the process.

Some people are somehow confused between the uses of belt sanders with that of belt grinders. To separate the two, remember that sanders are made for wood while grinders are specifically functional for metals. The three basic applications of belt grinders are broken down as follows: finishing for surface roughness, polishing and cosmetic finishes; stock removal such as tool mark removal and cleaning of corrosion; and deburring like edge breaking.

Bench grinders

These are types of grinding tools that perform with the use of two wheels instead of one. They are essential in any type of finishing or roughing processes. They are termed as such because of the usage of a workbench during the bench grinding process. They are vital in forming a shape out of tool bits and other tools needing repair. At times, they are also known as pedestal grinders.

Other types of grinders

Aside from the first two types of grinders, there are also cylindrical, surface, and jig grinders. The cylindrical grinder is made of various abrasive or grinding wheels and is used to form a cylinder out of a work piece. The surface grinder on the other hand, is helpful in order to produce a smooth and flat finish out of a metallic or non-metallic surface. The last type of grinding tools, the jig grinders, is made for dies, fixtures and jigs.
